I'm replacing the rear main on my '57 sedan with the original 235. All the parts stores around here (NAPA, Advanced Auto, Autozone) tell me that the replacement is a rubber seal. I've read discussion on this board that say my rear main is not machined for a rubber seal. Any advise? If I install the felpro rubber seal, will it leak? Can I install it without removing the crank like you can do with the rope seal? Or should I hold off and try to find the rope seal somewhere else? Many Thanks!
